Architectural drawing showing the names of the scientists and other learned people on the exterior of the tower, Gustave Eiffel's office, and the cupola. Eiffel (1832-1923) designed the world-famous tower, built for the International Exhibition of Paris in 1889, commemorating the centenary of the French Revolution. The tower consists of four curved iron piers connected by a lattice of girders. Construction started in January 1887 and was complete on 31 March 1889. It was further enlarged for the 1937 exhibition.
